• Never modify the unit by removing any of the safety guards or by-passing any of the safety interlock keys.
• Do not install in a location that is unable to support the weight of the unit. Personal injury and property damage may result from the unit falling.
• Before carrying out electrical work, attach an approved cable to the power supply cable. And make sure the equipment is grounded.
• For installation, use tools and piping materials manufactured exclusively for the R410A, and install it safely according to the instructions in this Installation Manual. The pressure of the HFC R410A refrigerant becomes approximately 1.6 times higher than that of the conventional refrigerant. For this reason, if the piping is not made with exclusive material or if an incomplete installation is carried out, a rupture or personal injury may occur, as well as water leaks, electric shocks and fires.
• When installing or moving the air conditioner, do not mix air with the specified refrigerant (R410A) within the refrigeration cycle. If there is a mixture with air, the pressure in the refrigeration cycle may become excessively high, and personal injury may occur due to its rupture.
